Introduction

In Dr. Glen Brown’s Nine-Laws Framework, Law 2: Weighted Decay of DAATS (WDHDI) harnesses quantum-inspired exponential smoothing to filter out market “noise” while preserving genuine volatility regimes. Strategy 2: Global Quick Trend Trader is designed to seize rapid trends on the M5 chart, with confirmations from M5, M15, M30, and M60. By marrying Law 2’s dissipative half-life dynamics with Strategy 2’s full default logic—color-coded EMA zones, Heiken Ashi Smoothed (HAS) indicators, MACD/GMACD, ITrend, ADX, and PATS-Stop—we create a robust “Quantum Smoothing Trend Trader” that enters trends cleanly and adapts stops fluidly. This article delivers:

• Foundational definitions of quantum decay analogies and trading indicators
• Mathematical derivation of WDHDI’s time-varying half-life and decay constant
• Step-by-step GATS implementation of Law 2 smoothing
• Complete default parameters for the Global Quick Trend Trader

1. Core Definitions & Concepts

1.1 Exponential Decay & Half-Life

Half-Life (τ) in quantum systems is the time required for a state’s amplitude to reduce by half under dissipative processes. In trading, we model the DAATS trailing stop’s responsiveness by assigning a time-varying half-life τ(t), so spikes in volatility smooth quickly, while calm periods maintain tighter stops.

1.2 Lindblad Dissipator

In open quantum systems, the Lindblad dissipator term 𝒟[L](ρ) governs irreversible decay. We abstract this to DAATS smoothing: each new bar applies a weighted decay factor, reducing the impact of transient spikes while preserving persistent volatility regimes.

1.3 DAATS & Weighted Decay

• DAATS: Multiplier × ATR(n), with n = EMA-zone boundary (8, 15, 25, 50, 89, 140, 200).
• Weighted Decay: γ₂(t) = ln 2 / τ(t), where τ(t)=τ₀/[1+β·ATR(t)]. We choose τ₀=20 bars, β=1.0 by default.

1.4 Global Quick Trend Trader Defaults

Strategy 2 enters on M5 when multiple conditions align across M5–M60:

• Price in bullish/bearish color-coded EMA zone
• HAS candles/time bars confirm trend direction
• Fast MACD (8,17,5) tuned per EMA zone
• ITrend & ADX (≥18) confirm momentum
• Global GMACD components aligned
• PATS-Stop validates support/resistance
• DAATS base stop = 15×ATR(n) (or 16×ATR(n))
• Profit target = 5×StopDistance (75–80×ATR(n))
• Risk per trade = 0.02%–2% of equity
• Break-Even at 32.875%×(0.6375×DAATS)

2. Law 2: Weighted Decay of DAATS (WDHDI)

Objective: Smooth DAATS spikes adaptively, preserving stop integrity during calm periods and reducing overshoot during volatility bursts.

2.1 Mathematical Derivation

Starting from the Lindblad form for dissipation:

dρ/dt = -i[H,ρ] + ∑𝒟[Lm](ρ)

we map the dissipator’s decay rate to the DAATS trailing stop:

τ(t) = τ₀ / [1 + β·ATR(t)]
γ₂(t) = ln(2) / τ(t)
DAATS<sub>new</sub> = DAATS<sub>prev</sub> · e^(−γ₂·Δt)

• τ₀: Base half-life (default 20 bars)
• β: Volatility scaling (default 1.0)
• Δt: Time increment (1 bar)

2.2 Implementation Steps in GATS

1. At each M5 bar, compute ATR(t).
2. Compute τ(t) = 20 / [1 + ATR(t)].
3. Compute γ₂ = ln(2)/τ(t).
4. Update DAATS as: DAATS ← DAATS × e^(−γ₂).
5. Use updated DAATS for stop-loss and Break-Even calculations.

2.3 Parameter Guidelines

3. Strategy 2: Global Quick Trend Trader Defaults

3.1 Buy Signal Criteria

1. Price in bullish EMA zone (above EMA n).
2. HAS candles & time bars (M5–M60) are Blue.
3. ITrend: Green > Red.
4. ADX ≥ 18.
5. Global GMACD (8,17,5) all bullish.
6. PATS-Stop below price.
7. λ ≤ λ_c (per Law 1, if active).

3.2 Sell Signal Criteria

1. Price in bearish EMA zone.
2. HAS candles & time bars Red.
3. ITrend: Green < Red.
4. ADX ≥ 18.
5. GMACD bearish.
6. PATS-Stop above price.
7. λ ≤ λ_c.

3.3 Stop-Loss, BE & Profit-Target

• Base DAATS: 15×ATR(n) or 16×ATR(n)
• Smoothed DAATS: apply exponential decay via γ₂(t)
• Break-Even: 0.32875 × (0.6375 × DAATS)
• Profit Target: 5×StopDistance → 75–80×ATR(n)
• Risk: 0.02%–2% of equity per trade

4. Quantum Narratives & Decoherence Channels

Observer Role: At each bar, the GATS engine samples ATR, EMAs, HAS, ADX, etc.—collapsing the market’s superposed volatility scenarios into a single stop-distance and trading decision.

• Decoherence Channel: γ₂(t) acts like a Lindblad operator, extinguishing transient volatility spikes and preserving only persistent trends.
• Entanglement: Confirmations across M5, M15, M30, M60 entangle conditions—requiring simultaneous satisfaction for trade entry.
• Measurement Impact: Adjusting DAATS reshapes subsequent price trajectories, as stop-levels influence market orders and liquidity.

// Law 2 settings
TAU0 = 20
BETA = 1.0

// Strategy 2 settings
EMA_ZONES = [8,15,25,50,89,140,200]
DAATS_MULT = 15

function onBar(M5) {
  zone = getEMAZone()
  atr = ATR(zone)
  tau = TAU0 / (1 + BETA * atr)
  gamma2 = Math.log(2) / tau
  daats = previousDAATS * Math.exp(-gamma2)

  if (isGlobalBuy() && canEnter(daats)) enterLong()
  if (isGlobalSell() && canEnter(daats)) enterShort()

  if (inPosition()) {
    setStopLoss(daats)
    setBreakEven(0.32875 * (0.6375 * daats))
    setProfitTarget(daats * 5)
